Black Sabbath frontman and general global superstar, Ozzy Osbourne has been diagnosed with Parkin Syndrome, a hereditary condition that affects the nervous system.

It was widely assumed that the prince of darkness' famous tremors were the result of his drug fuelled past life, but it now appears that the condition is a medical one.

A quote from Ozzy said: "I'd always assumed it was the booze and stuff. Now I've found it all stems from the family. It's called Parkin but it's not Parkinson's. Anything to do with the central nervous system has the word Parkin in it. A doctor in Los Angeles tried to tell me I had multiple sclerosis. And I believed him until I had a second opinion. When I told my sisters she said, 'Not you as well? Mum had that and Auntie Elsie and your grandma.' I'm like, 'Thanks for fucking telling me'. Me walking around thinking I've got some drug paralysis."
